I think going either digital or physical has their merits.
When it comes to digital, it is awfully sweet having the ability to play anything you want as fast as possible and not need to worry of the extra space outside the system to hold your games and to put the games in and get it to work from the media reader.
But physical media is also amazing to have as it is literally something you could hold on to and know that it is yours. Especially if you held on to it for so long, where after so many years, you could go to where you stored the games, hold that old game on your hand, plop it right in, and enjoy that game. I guess it is like music, for sure you could enjoy music from a digital service no problem in the highest quality possible, but holding onto records, CDs and cassette tapes is like an appreciation to the media and get to experience that media as is was made to be experienced.
I just think that the PS5 could be the last one we could enjoy both in the large scale and get ready to jump into a more digital market in the future. It is the more convenient and less costly option, but it does definitely make physical media a more luxurious and appreciative option in the future.
